IMPROVEMENT IN SPRING-SEATS FOR'WAGONS.

Specification forming part of Letters Patent No. 118,385, dated August22, 1871.

To all whom it may concern: Be it known that I, AMBRosE S. NEWMAN, ofPlymouth, in the county of Hancock and in the State of Illinois, havein\fented certain new and useful Improvements in Spring-Seats forWagons, Svc.; and do hereby declare that the following is a full, clear,and exact description thereof, reference being had to the accompanyingdrawing and to the letters of reference marked thereon making a part ofthis specification.

The nature of my invention consists in the construction and arrangementof a spring-seat and spring footboard for railroad cars`aiidwveh'icleslof any description, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, Iwill now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure lis a front view, and Fig. 2 a transverse vertical section.

A A represent two boards of proper thickness securely fastened in thecenter, either with or without a bar, B, between them. On each side ofthe center is then forced in a round bar, C, forming an adjustablefulcrum, which completes one set of springs with only one leaf. It is,of course, evident that, if desired or necessary, two or more leaves ofdifferent lengths may just as well be used. Another set ofsimilarly-constructed springs may be fastened onto the rst set by meansof cross-bars D D at the ends, as shown, and, so on, as many sets as maybe desired can be added. In fact, they can be multiplied so as to form acombined spring that an ounce-weight would set in motion. On top of theupper set of springs is placed an extra board, E, which forms the seatproper. The lower spring is attached at its ends to cross-bars G G,which project a short rdistance in front, as seen in Fig. 2, and on topof the lower spring at each end is fastened a springbar, H, betweenwhich and the cross-bar G isinserted a movable fulcrum, D. The frontends of the bars H H are connected by a foot-board, I. The wagon-seatthus constructed may rest on the bottom of the box inside the sideboards, or it may be made with only two or three boards and rest on thetop of the box or on spring-bars on the inside of the box. Forcar-seats, a back can readily be supplied. The top-board E, as well asthe foot-board I, will warp down more or less by usage; but this isremedied by turning them over when necessary. The others will never change but a trifle, for the manner in which they are bent causes thepressure to act directly opposite to the weight when in use.

Having thus full y described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

l.` One or more sets of springs, each composed of two boards, A A,connected in the center, with or without the cross-bar B between them,and provided with movable fulcrinns O O, substantially as and for thepurposes herein set forth.

2. The spring-bars H H, foot-bar I, and fulerums D D, constructed andarranged sub stantially as and for the purposes herein set forth.

. 3. A wagon or ear-seat, composed of boards A A, fulcrums C O, topboard E, spring foot` board H I, and fulcrums D D, all constructed,combined, and arranged substantially as and for the purposes herein setforth.

In testimony that I claim the foregoing I have hereunto set my handA andseal this 27th day of May, 1871.
